Q:What is the reason that the single phase AC motor is turned on and off?

Check the switch first, is there any bad contact?. After the problem of the switch is removed, the power is turned on, and whether the cold state can run normally every time. If there is a phenomenon that the cold condition can not work properly, the internal circuit or winding is not working.A single-phase alternating current motor is a rotating electromagnetic machine used to realize the conversion of electrical energy and mechanical energy.

Q:how they works?

ac .is alternating cu rant like in your house .dc is direct cu rant like in your car . both work the same DIFRNCE voltage

Q:I need some websites that show how a weed weaker motor works.

I'm assuming you mean a weed wacker, in which case there are two different motors to be considered. The first would be an electric, usually AC, motor. These motors work as expected, several coils of wires and magnets. Current flows through the wires inducing a magnetic field, the magnetic field interacts with the magnets and the motor turns. The other type is gasoline driven. Because these machines are relatively small and handheld they typically use a two stroke engine. There is a link to a document below that should give you an understanding of how the two stroke motor works.

Q:Why AC motor speed control system will replace DC motor speed regulation system?

At present has been put forward and the practical application of the PWM control scheme is more than a dozen kinds, about PWM control technology in the power of many famous international conferences, such as PESC, IECON, EPE annual meeting has formed a special. Especially the microprocessor used in PWM technology and the digital pattern, is constantly changing, from the initial pursuit of sinusoidal voltage waveform, sine to current waveforms, then to sinusoidal flux; from the optimal efficiency, minimum torque ripple, to eliminate noise, PWM control technology development has experienced a continuous innovation and the continuous improvement process. So far, new proposals have been put forward, which further proves that the research of this technology is in the ascendant.

Q:dc motors ac motorsbrushesstepper motor

i would imagine it is AC motors because mobile robots are powered by batteries. batteries produce DC current which would operate the dc motor. it is possible that AC is used, but seems like it would be overly complicated =/

Q:I have a 1999 Kia Sportage 4WD 2.0L I-4

normally the blower motor is located underneath the dash on the passenger side by the floorboard of the vehicle

Q:What are the demerits of two phase ac motors?

Theres actually no such thing as a two phase motor. If a motor has two hot wires connected to it it is considered a single phase.

Q:I am trying to wire up a salvaged AC motor for a lab project. It is a single phase 1/3 HP 115 volt 6.9 amp motor with four wires coming out of it and no schematic... It would seem that the wires are somehow paired as they come out of the motor, T0 and T5 are together, and T1 and T8 are together. The motor has a set of brushes so I assume it is a universal motor. Before I go hooking it up all willy-nilly like, I was wondering if anyone could shed a little insight on this problem. Also, I assume that this motor is reversible, so if anyone could give me a little help on that I would be grateful.

ya motor might want to o.k. be a stepping motor run by technique of a chip that aspects a pulsed provide around the three wires which it reverses by technique of reversing the pulses reminiscent of a lightchaser in case you go with to flow into this further attempt googling this chip- SAA 1027

Q:i hear about dc motors an a lot so what is ac and dc !

ac means Alternating Current as the name suggests the current value keeps on changing(generally from +ve peak to -ve peak with in a fraction of time) dc means Direct current , this type of current gives constant voltage or current without any fluctuations

Q:When a small AC motor is operating at rated load from a 115V, 60-cycle source, it takes 287 watts at a lagging power factor of 0.6. a. Calculate the line current. b. What should be the capacitance of the capacitor connected in parallel with the motor that will make the power factor unity?. c. Determine the line current under this condition?

This will not be the first-rate reply. I feel you may have two questions right here. You could have a 3/four hp motor a good way to draw 13Amp on a hundred and fifteen volts at 60 Hearts or Cycles and that can be also wired by using changing the way in which it is attached to attract 6.5 Amps at 230 volts on 60 Cycles. Different query is set wire measurement involving voltage drop over 500 feet of distance. Determine out Ohm's law although it should no longer be used for basic a.C. Motor and transformer circuits or a circuit containing any e.M.F or voltage as opposed to the impressed voltage. (re all ref. - functional main of electricity.) One mile of copper wire a quarter of and inch diameter presents about 1 ohm resistance. . You must also query what number of wires you ought to run to your cable; whether it is one white one black and one inexperienced safeguard ground or the entire former and a pink besides . Be conscious that the smaller the quantity of the wire, the bigger the size of the wire; that a number six wire is far thicker than a quantity sixteen and that the previous offers less resistance. Getting an electrician to put all of those details collectively and hook up your water pump will keep you in good stead along with your insurance organization even supposing you understand how to do the job yourself as well as keep you from burning out your motor.
